                                                                                                                                                                一、介紹

                                                                                                                                                                機器視覺是人工智能迅速發展的分支,簡單地說,機器視覺是用機器代替人眼進行測量和判斷

                                                                                                                                                              什么是機器視覺


                                                                                                                                                                互聯網的迅速發展,物流業得到了迅速的發展。 不僅是每年一度的京東購物節和淘寶節,物流工作人員都高壓不堪,喘不過氣來。 現在的日??爝f,甚至超市送貨上門的人員都在急劇增加。 美團快遞配置無人物流,京東機器人物流揀貨已經應用,機器人的工作,給人們的生活帶來了很大的便利,機器人逐漸成為市場的寵兒。

                                                                                                                                                                二、系統結構

                                                                                                                                                                照明

                                                                                                                                                                照明是影響機器視覺系統輸入的重要因素,它直接影響輸入數據的質量和應用效果。 由于沒有通用的機器視覺照明設備,每個特定的應用實例都必須選擇相應的照明裝置以達到最佳效果。 光源分為可見光和不可見光,常用的幾種可見光源為白色標記燈、熒光燈、汞燈和鈉光,可見光的缺點是光能不穩定;

                                                                                                                                                                要使光能穩定到一定程度,是實用化過程中亟待解決的問題。 另一方面,環境光有可能影響圖像的質量,因此,通過安裝防護屏可以降低環境光的影響。 照明系統根據其照射方法分為背光、前方照明、結構光、閃光燈照明等。 其中,背光燈的優點是通過在光源和照相機之間放置被測量物,可以得到對比度高的圖像。 前方照明由于光源和照相機在被測量物的同一側,所以安裝很容易。 結構光照明將光幕和線光源等投影到被測量物上,根據它們產生的變形解調被測量物的三維信息。 閃光燈照明用高頻光脈沖照射物體。 照相機拍攝要求與光源同步。
